Where Is Blockchain Going Next?

As we mentioned above, blockchain is a distributed, digital ledger. The database exists in multiple copies across multiple computers. Each of these copies is identical. Today, organizations maintain centralized databases and servers where all their data is held.

This makes these servers a lucrative target for hackers. Blockchain decentralizes data and makes it public but encrypted. Many people believe this makes it tamper-proof. When a transaction occurs on the blockchain, data about that new transaction must be sent to all computers — nodes — on the network. Another key feature of blockchain is that each transaction on the blockchain is signed digitally, using public key cryptography.

Public key cryptography involves the use of two keys — a public and private key. The public key is used to sign and encrypt the sent message, and anyone can see this key.

However, only the recipient has the private key, which means only the recipient can decrypt the transaction. Public keys are used for more than just encrypting messages: Each block in the blockchain consists of a list of transactions.

Each block also contains a block header. Headers contain three sets of metadata, including structured data about the transactions in the block; a timestamp and proof-of-work algorithm data; and a reference to the parent block, or previous block, using a hash.

You may have heard of bitcoin mining. Mining is the process by which new blocks are created on the blockchain. In Bitcoin, a new block is mined every 10 minutes. Some cryptocurrencies have a faster block transaction time, while others have a slower time. Essentially, this means that a Bitcoin transaction takes a maximum of 10 minutes to process. Mining validates each new transaction on the blockchain.

In order to do that, the miner which is a computer or processor solves a unique, difficult math puzzle. These puzzles require enormous computational power. Since Bitcoin was first introduced, the difficulty of these puzzles has increased exponentially, which means more power than ever is needed to solve the puzzles.

To put the computational power into perspective, miners were tracked trying thousand trillion solutions per second to solve the puzzles — and that was all the way back in October as reported by The Economist. Why would someone spend all this computational power on math puzzles? Miners receive a set amount of cryptocurrency for every block that is mined, along with a cut of the transaction fees for all transactions in the block. You could write thousands of pages on the history of blockchain technology, including all of the minor improvements, major leaps, and companies formed over the past decade.

The first mention of blockchain can be found in the original source code for Bitcoin. You can view the original code for bitcoin on Github. It was the first time we saw the impact of blockchain technology on the world around us. Soon after, in April , Satoshi disappeared from the internet and stopped contributing to bitcoin forums, papers, or code.

Investors surged into bitcoin and blockchain-related startups. Over the years since, other cryptocurrencies have been created. Litecoin and Dogecoin were two of the first to appear, for example. Today, Ethereum holds a solid position as the number two spot behind bitcoin. There have been a number of innovations over the history of blockchain. Those innovations include all of the following:. The second innovation is when people realized that the underlying technology behind bitcoin — the blockchain — could be used for more than just bitcoin.

People realized it could be used for other cryptocurrencies, for example, or for a wide range of other industries and purposes. This is where the history of blockchain technology and innovation really took off.

The second major blockchain platform after Bitcoin was the Ethereum blockchain. The primary advantage of the Ethereum blockchain over previous blockchains was the smart contract system.

Essentially, this involved building small computer programs directly in the blockchain. This allowed conventional financial tools — like loans or bonds — to be represented on the blockchain, instead of just bitcoins and cryptocurrencies. Proof of stake started appearing in late and early Today, most blockchains are secured by Proof of Work, which means the group with the largest computing power makes the decisions i.

New blockchain technology replaces this with proof of stake. Scaled blockchain technology will accelerate blockchain processing in the future. Today, blockchain technology requires every computer in the network to process every transaction.

This is slow and inefficient. Scaled blockchain technology will accelerate the process by determining the precise number of computers needed to process each transaction, and then utilizing other computers for other tasks.

And all of this innovation can be traced back to Satoshi Nakamoto. In that paper, Satoshi describes the basis for blockchain technology.

All blockchain innovations can be traced back to Satoshi Nakamoto. Who is Satoshi Nakamoto? Or he could be a group of individuals. Here are some of the things we know — or think we know — about the mysterious creator of blockchain:. Ultimately, the inventor of blockchain technology may never be known. Or, it could be one of the names listed above. Until the mystery is solved, it will play an increasingly interesting role in the myth behind bitcoin.

Innovations in blockchain have made it increasingly attractive — and usable — to organizations outside the cryptocurrency world. Financial institutions, political organizations, cloud storage providers, and even online casinos have all started using blockchain technology.
